WASHINGTON, ASSIG'NOR Q'F TWO-THIRDS TO OTTO WILL, OF SEATTLE, WASHINGTON.

GRINDING AND POLISH ING MAC HINE.

To all whom it may concern:

Be it known that I, CARL A. WILL, a citizen of the United States; residing at Seattle, in the county of King, State of "Washington, have invented certain new and useful improvements in Grinding and Polishing Machines; and I do hereby declare the 'following to be a full, clear, and exact description of the invention, such as Will enable others skilled in the art to which it appertains to" wheel is mounted so that the rotation of the grinding wheel and the reciprocation of the work carrier will be accomplished through theinstrument ality of a common means.

A. further object of the invention resides in providing means whereby the connection between the worl carrier and the rotary shaft carrying the grinding wheel may be disengaged and the grinding wheel operated independently of the work carrier.

A still further object of the invention resides in the provision of improved means for effecting the polishing and securing ot' the work after the same has been acted upon by the grinding wheel.

lVith these and other objects in view, the invention consists in the details of construction and in the arrangement and combination of parts to be hereinal'lcr more fully described and particularly pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters of reiterence denote corresponding parts in the several views; and in which,

Figure 1 is a plan view of a grinding and polishing machine constructed in accordance with the invention; Fig. 2, a trout view of same; Fig. 3, a section on the line 3-3 of Fig. 1 l ig. l, a section. on the line 4*4 of Fig. 1; Fig. 5, an enlarged section on the line 55 of Fig. 2; Fig. (3, an enlarged Specification of Letters Patent.

side View of thework carrier and the upper endof its support; and Fig. 7, a partial longitudinal section through the connection between the grinding Wheel support andthe work carrier support.

Referring to the drawings, the invention is shown as comprising a base ldftrorn which rises a standard 11. This base is also provided with a laterally extending portion 12 which has formed therein a groove 18 for apurpose that will presently appear. This groove hasformed in its lower side openings 14 and 15, thepurpose of whichwill presi entlyappearf Journaled in the standard 11- is a shaft 16 which. has fixed on. one end thereof a grinding Wheel 17 operated by a handle 18. This shaft 16 is also supported by a brace journal 19 projecting laterally lot the standard 11. Also fixed on the shatt 1.6.is one section of a polishing wheel 20.

V V Screwed mto the end or the shaft 16 aeriacent the wheel 20 1s a section 2]. which has fixed on its inner end a section of the polishing wheel, the sections 21 and 22 being designed to form a complete polishing wheel and have their adjacent'taces covered with leather or any suitable polishing material. The distance between the sections 21 and is regulated by screwing the shaft section 21 into the shaft 16. Mounted on the extr'eme outer end of the shaft section 21. is a cloth scourin Wheel 23 of the usual con struction. I l so fixed on the shaft 16 be tween the grinding wheel 17 andthe standard 11 is a gear Wheel 24 which meshes'with a gear wheel 25 journaled on an extension. 26 of the standard 11. Slidably mounted in the groove 1.3 is a base section 27 from which rises a standard 28. .l'ournaled in this-stand ard 28 is a shaft 29 which has fixed thereon a segmental gear 30. Secured to this segmental gear and arranged concentrically with respect to the shaft 29 is a crown gear 31 which meshes with the gear 25 so that the rotation of the shaft 16. will. produce a rotation of the crown gear 31' and the seg mental gear 30. Supported by the standard 2% and disposed hmgitudinally of the grinding wheel 17 is a frame A which includes parallel rods 32 and'33. Slidably mounted upon the rods and is a sliding block 3% which has detachably mounted in its upper end a work carrier support 35, while a mangle rack 36 is rigidly secured to the upperend of the block 34 and operatively engages the segmental gear'SO so'that the rotation of said gear will effect-a reciprocation of the rack 36 and likewise the block 34 and the support 35. The upper end of the support 35 is forked to form the arms 37 and 37'.

The work carrier is shown as comprising a pair of plates. 38 and 39 which are connected together by a screw member 40 whereby said plates may be clamped together upon the work disposed therebetween. The plate 39 has extending from its lower face an car 41 which is positioned between the arms 37 and 37 of the support 35, and pivotally connected to said support by means of a pivot pin 42 extending through said arms and said ear. Fixed on the pivot pin 42 adjacent one side of the support is a toothed plate 43, upon one edge of which the plate 39 is-adapted to rest. A pawl 44 pivoted to the support 35 is adapted to engage the teeth oft-he plate .43 and hold said plate in a desired position so'as to effect the proper adjustment of the work carrier. After the adjustment of the plate '43, the work carrier is yieldingly held in engagement with one edge thereof by means of a spring 45, one end of which is secured to the lower face of the plate 39 and the "other end to the supp ort 35. By the construction so far described it wilkh-e apparent that upon the rotation of p the shaft 16, the rack 36 will be reeiproeated longitudinally of the grinding wheel 17 and damn this reciprocation, the work carrier will a so be reclprocated longitudinally of theigrinding wheel 17. and traverse the periphery of the latter and effect the proper ien grinding of the work carried thereby. W

it is' des red to operate the grinding wheel 17 independently of the work carrier, the base member 27 is moved in the groove 13 so as to shift the crown gear 31 out of engagement with the gear 25, said base member carryin a screw 47 which is adapted to be manipu ated into the opening 15 when the gear 25 is in engagement with the gear 31, and into the opening 14 when said gears 25 and 31 have been moved out of engagement with each other.

What is claimed is 1. In a device of the class described, the combination of a frame, a shaft journaled on the frame, a grinding wheel fixed on said; shaft, means for rotating said shaft, a mangle rack mechanism mounted, on said frame having its reciprocating member movable longitudinally of the grinding wheel, connections between the shaft and said mangle rack mechanism whereby the rotation of the former will actuate the latter, and a work carrier mounted on the reciproeating member of the mangle rack mechamsm.

2. In a device of the class described, the combination of a frame, a shaft journaled on the frame, a. grinding wheel fixed on the shaft, means for rotatin said shaft, 9. work carrier support mounted on the frame for reciprocation longitudinally of the grinding wheel, connections between the work carrier support and the shaft for effecting the recipr cation of the former by the rotation of the latter, said support having a forked upper end, a work carrier comprising a pair of plates, connections between said plates for clamping same together, an ear extending'from one of said plates and dispose between the arms of the forked end of the support, a pivot pin extending through said arms and said ear whereby the work carrier is pivotally connected to the support, a toothed plate mounted on said pivot pin and adapted to support the work carrier, a pawl mounted on said support for engaging said toothed plate to hold same against movement under the influence of the weight of said work carrier, and spring actuated means constantly tendin to force said carrier into engagement wit said plate.

-In testimony whereof, I afiix my sigma ture, in presence of two witnesses.
